Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV equipped with an infrared search device for unexploded ordnance. Background Technology

[0002] In areas following live-fire exercises or at sites where blasting operations have been conducted, a large number of unexploded ordnance (OPEs) often remain. These OPEs pose a serious threat to personnel safety. Traditional OPE search methods, such as manual search, are inefficient and extremely dangerous, requiring personnel to come into close contact with OPEs; if an explosion occurs, the consequences would be unimaginable. Using large detection vehicles is difficult to implement in areas with complex terrain and poor transportation, or OPE searches cannot be conducted at night due to limitations in conditions.

[0003] Existing drones have insufficient detection accuracy in searching for unexploded ordnance, failing to meet the actual need for efficient unexploded ordnance searches. In addition, the existing drones are connected to infrared thermal imagers via screws, which makes installation and disassembly cumbersome and inconvenient for retrieval, storage, maintenance, and repair. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art by proposing a drone-mounted infrared search device for unexploded ordnance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a drone with built-in infrared search device for unexploded ordnance, including a drone, a mounting base, an infrared thermal imager, a connecting component, and an adjusting component. The mounting base is located below the drone, the connecting component is located on the outer side of the mounting base, the adjusting component is located below the mounting base, and the infrared thermal imager is located in the middle of the adjusting component. The adjusting component includes a connecting block, an adjusting base, a dual-head motor, a gear, an incomplete gear ring, and a guide block.

[0007] An adjusting seat is fixedly installed at the lower end of the connecting block. A dual-head motor is fixedly installed in the middle of the adjusting seat. The output shafts of the dual-head motors are rotatably connected to the adjusting seat on both sides. The output shaft ends of the dual-head motors are fixedly connected to a gear. The outer wall of the gear meshes with an incomplete gear ring. One side of the incomplete gear ring is fixedly connected to a guide block. The outer walls of both guide blocks are slidably connected to the adjusting seat. The ends of both guide blocks are fixedly connected to an infrared thermal imager. Both sides of the infrared thermal imager are rotatably connected to the adjusting seat.

[0008] Preferably, the outer wall of the connecting block can be clearance-fitted with the mounting base.

[0009] Preferably, the connecting assembly includes a collar, a round rod, a positioning rod, and a spring;

[0010] The two ends of the spring are respectively connected to the UAV by collars, the inner wall of the collar is slidably connected to the mounting seat, the two sides of the collar are respectively fixedly connected to the round rod, and the outer wall of the round rod is slidably connected to the positioning rod.

[0011] Preferably, the positioning rod is inserted into the connecting block in the direction away from the round rod.

[0012] Preferably, the outer wall of the positioning rod is slidably connected to the mounting base.

[0013] The present invention proposes a drone with an integrated infrared unexploded ordnance (UFO) search device. The advantages of this device are: it controls a dual-head motor, whose output shaft drives gears on both sides to rotate simultaneously. These gears drive an incomplete gear ring, which in turn drives a guide block to move along a groove on an adjusting seat. The guide block then drives an infrared thermal imager to rotate, which in turn rotates along the adjusting seat, thereby adjusting the angle of the infrared thermal imager. This facilitates the detection and search for UFOs, improving detection accuracy and efficiency.

[0014] By moving the collar upwards, the collar compresses the spring, which in turn moves the round rod upwards. As the round rod moves upwards, it causes the positioning rod to move laterally, separating the positioning rod from the connecting block. This, in turn, separates the connecting block from the mounting base, enabling the rapid disassembly of the far-infrared thermal imager. This facilitates the recovery, storage, repair, and maintenance of the infrared thermal imager. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-4 A drone 1 with an infrared search device for unexploded ordnance includes a drone 1, a mounting base 2, an infrared thermal imager 4, a connecting component 3, and an adjusting component 5. The mounting base 2 is located below the drone 1, the connecting component 3 is located on the outer side of the mounting base 2, the adjusting component 5 is located below the mounting base 2, and the infrared thermal imager 4 is located in the middle of the adjusting component 5. The adjusting component 5 includes a connecting block 501, an adjusting base 502, a dual-head motor 503, a gear 504, an incomplete gear ring 505, and a guide block 506.

[0022] An adjusting seat 502 is fixedly installed at the lower end of the connecting block 501. A dual-head motor 503 is fixedly installed in the middle of the adjusting seat 502. The output shafts of the dual-head motor 503 are rotatably connected to the adjusting seat 502 on both sides. The ends of the output shafts of the dual-head motor 503 are fixedly connected to gears 504. The output shafts of the dual-head motor 503 drive the gears 504 on both sides to rotate simultaneously. The gears 504 drive the incomplete gear ring 505 to move. The incomplete gear ring 505 drives the guide block 506 to move along the slide groove of the adjusting seat 502. The guide block 506 drives the infrared thermal imager 4 to rotate. The infrared thermal imager 4 rotates along the adjusting seat 502, thereby adjusting the position of the infrared thermal imager. The angle of the infrared thermal imager 4 is adjusted. The infrared thermal imager 4 is connected to the data processing device, which is installed on the UAV. The data processing device includes a data processing module (existing technology) used to receive data collected by the infrared imager in real time and analyze and process the data through a specially designed algorithm. This algorithm can remove environmental interference factors, such as ground heat radiation and sunlight reflection, accurately identify the infrared characteristic signal of the unexploded ordnance, and determine the position coordinates of the unexploded ordnance. It also includes a communication and positioning module (existing technology) used to equip high-performance wireless communication equipment to transmit the unexploded ordnance position information detected by the UAV back to the ground control center in real time. Meanwhile, a high-precision satellite positioning system is used to accurately record the flight trajectory of the UAV and the position of unexploded ordnance, providing accurate data support for subsequent bomb disposal work. The outer wall of gear 504 meshes with the incomplete gear ring 505. One side of the incomplete gear ring 505 is fixedly connected to the guide block 506. The outer walls of both guide blocks 506 are slidably connected to the adjusting seat 502. The ends of both guide blocks 506 are fixedly connected to the infrared thermal imager 4. Both sides of the infrared thermal imager 4 are rotatably connected to the adjusting seat 502. The outer wall of the connecting block 501 can be clearance-fitted with the mounting seat 2.

[0023] The connecting assembly 3 includes a collar 301, a round rod 302, a positioning rod 303, and a spring 304. Both ends of the spring 304 are fixedly connected to the collar 301 and the drone 1, respectively. The inner wall of the collar 301 is slidably connected to the mounting seat 2. Both sides of the collar 301 are fixedly connected to the round rod 302, and the outer wall of the round rod 302 is slidably connected to the positioning rod 303. Figure 1 As shown, the collar 301 moves upward, causing the spring 304 to compress. At the same time, the collar 301 causes the round rod 302 to move upward. During the upward movement of the round rod 302, the positioning rod 303 moves laterally, causing the positioning rod 303 to separate from the connecting block 501, thereby separating the connecting block from the mounting base 2 and realizing the quick disassembly of the far-infrared thermal imager 4.

[0024] The positioning rod 303 is inserted into the connecting block 501 in the direction away from the round rod 302, and the outer wall of the positioning rod 303 is slidably connected to the mounting base 2. Figure 4 As shown, key blocks are provided on the upper and lower sides of the connecting block 501, and keyways matching the key blocks are provided on the upper and lower sides of the mounting base 2, for positioning the connecting block 501 and the mounting base 2, ensuring that the positioning rod 303 can accurately match the connecting block 501.

[0025] Specifically, the output shafts of the dual-head motors 305 and 503 drive the gears 504 on both sides to rotate simultaneously. The gears 504 drive the incomplete gear ring 505 to move. The incomplete gear ring 505 drives the guide block 506 to move along the slide groove of the adjusting seat 502. The guide block 506 drives the infrared thermal imager 4 to rotate. The infrared thermal imager 4 rotates along the adjusting seat 502, thereby adjusting the angle of the infrared thermal imager 4 to a suitable position. During the flight of the UAV 1, the infrared thermal imager 4 detects unexploded ordnance. The data processing device records the position and coordinates of the unexploded ordnance and transmits the data back to the terminal.

[0026] After use, the operator moves the collar 301 upwards, which compresses the spring 304. At the same time, the collar 301 moves the round rod 302 upwards. During the upward movement of the round rod 302, the positioning rod 303 moves laterally, causing the positioning rod 303 to separate from the connecting block 501. This separates the connecting block from the mounting base 2, enabling the rapid disassembly of the far-infrared thermal imager 4.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
